I agree totally I forget which bike series it is but even the 600's fit the 190 tyre now and the best of them are putting out 140/145 bhp So I would not recommend putting the 180 on your Blade :nono:
If you run NTECs on a 600 you use a 190 and on a thousand they're 195 but they're still quick turning but have massive side grip too
Without a doubt for it's Diablo Rosso Corsas, but I've been using Pirelli Diablos since 03. Word of warning on fitting a 55 profile, as it's not a recommended tyre size for the bike Insurance companies may not be happy if the bike is in an accident, anything to avoid a payout.!!!
